24、tside the competence of the CEN/CENELEC national member. This European Standard falls under Directive LVD (2006/95/EC). NOTE (from CEN/CENELEC IR Part 2:2006, 2.17) Where standards fall under EC Directives, it is the view of the Commission of the European Communities (OJ No C 59; 1982-03-09) that th

25、e effect of the decision of the Court of Justice in case 815/79 Cremonini/Vrankovich (European Court Reports 1980, p. 3583) is that compliance with A-deviations is no longer mandatory and that the free movement of products complying with such a standard should not be restricted except under the safe

26、guard procedure provided for in the relevant Directive. A-deviations in an EFTA-country are valid instead of the relevant provisions of the European Standard in that country until they have been removed.

33、requirements for CABINET X-RAY SYSTEMS. A CABINET X-RAY SYSTEM is a system that contains an X-ray tube installed in a cabinet which, independently of existing architectural structures except the floor on which it may be placed, is intended to contain at least that portion of a material being irradia

34、ted, provide radiation attenuation, and exclude personnel from the interior during generation of X-radiation. These CABINET X-RAY SYSTEMS are used in industrial, commercial, and public environments, for example, to inspect materials, to analyze materials, and to screen baggage. 1.1.2 Equipment exclu

35、ded from scope Addition: Add the following new items to the list: aa) equipment intended to apply X-radiation to humans or animals; bb) equipment incorporating an X-ray tube but not incorporating complete shielding against X-radiation hazards, such as: 1) equipment intended to be used within a shiel

36、ded room which excludes personnel during operation; 2) equipment intended to be used with separate portable or temporary shielding; 3) equipment intended to produce an emerging beam of X-radiation. 1.2.1 Aspects included in scope Addition: Add the following text at the end of the first paragraph: Th

45、e equipment shall be marked at the location of each control which may be used to initiate X-ray generation, with the text, “Caution: X-rays generated when activated”, or substantially similar text. Equipment shall be marked adjacent to each PORT which is sufficiently large to admit human body parts

46、to the direct X-ray beam, with the text, “Caution: X-ray hazard. Do not insert any part of the body when system is activated”, or substantially similar text. The indicators required by 5.1.102 shall be marked “X-ray on”, or equivalent. NOTE 1 If a milliammeter is used as one of the required indicato

47、rs, it is marked as specified in 5.1.102, and is not marked “X-ray on”. For CABINET X-RAY SYSTEMS designed so that humans may enter the cabinet for specified purposes, permanent markings shall be provided inside the cabinet to describe the function of the signals and controls required by 5.1.102 c)

48、and 5.1.102 d). NOTE 2 National regulations may require a nationally-accepted language for safety instructions and markings. Conformity is checked by inspection. 5.1.102 Indicators and annunciators for CABINET X-RAY SYSTEMS The equipment shall include all of the following indicators and annunciators

49、. a) Two independent means to indicate when X-rays are being generated, located so that at least one indicator is discernible from any location at which the initiation of X-ray generation is possible. The indicators shall be activated only when X-rays are being generated, except that if the X-ray generation period is less than 0,5 s, then the indicator shall be activated for at least 0,5 s. No SINGLE FAULT CONDITION shall disable both indicators. A combination of software, hardware and digital control may be used to gen
